Study on Experiment and Simulation for Laser Surface Micro Texturing on Cylinder Piston Ring Friction Pair

Abstract:

Regarding the cylinder piston ring friction pair system as the object , put forward a new numerical simulation method to study the thermal effect mechanism of single pulse interval laser micro texturing. By means of numerical simulation and experimental verification, analysis the variation of laser pulse frequency and laser power on the 45# steel surface micro cavity morphology. The simulation and experimental results show that along with the increase of laser pulse number, the depth of micro cavity increases, the recasting phenomenon of molten metal is obvious, and the machined surface quality decreases. At the same condition, the micro cavity depth simulation results and experimental results are basically the same trend; the maximum error is less than 8%, which proves the feasibility and validity of the numerical simulation method.
